Hi everyone.
I’m trying to create a randomness function in a Patch to randomize the value of some parameters.
The idea is to create a button that sends a fixed value between 0 to 1 when you press it. I checked the Random node but I don’t know if exist a way to control it and tell him when he should send a new value.
Thanks in advance!!
Welcome to the Forum @jjos. Glad you could join us! The random node continuously generates random values between 0 and 1 (noise). In order to get a specific random value on-demand, connect the random node to the input of a Sample and Hold node. When you trigger the S&H the output will be a random value.
The random node actually produces the same series of random numbers every time it is loaded. If this presents a problem you can change the seed value which will change the random sequence. Generally this only matters when you are using multiple random nodes in a patch.

Thanks a lot! I’m going to try it right away 
Is possible to save the Seed setting of the random node with the patch?
The seed value will be saved with the patch.
Umm. Everytime I load the patch the seed value comes back to 0. I’m on the ios version.
I just tested it and it seems to save fine for me on both iOS and macOS. Try creating a blank patch, adding a random node, changing the seed value then closing the patch. Re-open the patch and see if it has reset. For me it stays at whatever value I’ve set it to.

Is working with an empty patch. Thanks!
